Earlier this year, the company had announced plans to construct a small network of fueling stations in the Northeast, marking the first significant expansion of U.S. hydrogen infrastructure outside California.

Similar to charging-station apps from Plugshare, ChargePoint, and others, Air Liquide's locator app lets drivers find the nearest hydrogen fueling station, and check its status.

The app also allows users to rate and review stations, and participate in an online community.
